This special section of the ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems: Part B comprises seven papers related to recent advances and emerging approaches on the risk and uncertainties that are associated with the fast-changing sector of offshore renewable energy. A concerted effort was made to achieve broad geographic representation, with thematic and methodological diversity, variety in industrial needs. The papers present developments in both fundamental research and engineering applications and are expected to be a snapshot in time around the risks and uncertainties of this topic.
